Researchers discover bacteria thrive in zero-gravity low nutrient environment

(Phys.org) —A team of researchers at Rensselaer Polytechnic Institute, in New York, working with Lockheed-Martin Ames Research Center has found that one strain of a common type of bacteria thrives aboard space vehicles, even when faced with minimal nutrients. In their paper published in BMC Microbiology, the researchers describe an experiment they conducted aboard NASA Shuttle Atlantis that showed that Pseudomonas aeruginosa, a very common type of bacteria, grows more dense cultures when in space than it does on Earth when available nutrients are restricted.
